Had 37's on my 2021 350 with the Carli Backcountry and loved it. 37's my vote

37s fit a truck nicely. That’s my vote.

if you tow at the upper end of the capacity frequently you might have some internal debating to do. If I was towing 15000lbs across the country regularly I would stick to the stock size honestly.

I have a gas engine on 37s and I’ve towed heavier with it just fine. It doesn’t win a race but it had pulled a dump trailer at the trucks limit and got the job done. I also don’t generally pull heavier loads more than 50-10miles down the road so that helps.

just depends on what you’re after but I think even 37s can look small sometimes.

If I had just fitted a full Carli kit like that I would for sure be running the 37's. The 4.30 gears and the super low first of the ten speed will easily handle the tires you selected. I run 35's on stock suspension and 3.73's and the truck is a rocket, even at high altitude where I live. I also need to run tire chain in the winter, barring that requirement, 37's for sure.

maybe not at the grocery store but what about offroad. and with what rim offset or diam. and what tire brand and model . theres alot of variables for a blanket statement

In over a million miles of driving, I've dropped the spare tire on my vehicles exactly zero times. I've had half a dozen different punctures over the years, but it's really easy to plug a tire on the spot and move on.

Now trailer blowouts, that's a different story...

I have a Carli kit sitting in my garage as well because I have yet to decide what tires to get. I do think 37’s look best but boy do I not want to hve to deal with rubbing, etc.

Is there not any Metric inbetween sizes?

As far as power loss, look at the actual weight of the tire too. Really important.

If I had a gasser that wasn’t heavy loaded ever I would even run an E1 or D 121 as that should match the rear GAWR.

After agonizing between 35 vs 37 I decided to go with a bit more aggressive tread and chose the Toyo 35x12.5x18 RT trail mounted on 18x9 +18 Method 305 NV Im happy with the way it turned out, at least for now.

Looks good. If you ever get tired of those you can go with a 315/70/18 which is about exactly inbetween a ‘35’ and ‘37’ in height and the same width or .1 inch skinner depending on brand.

There are 2 metric in-between sizes.

295/65/20 is basically a 36x11

325/60/20 is a 36x13.
